(CL 221-11) This invention is an improved reversible plug preferred to curl the end of the cylindrical porand pouring spout for a container. tion It inwardly to provide a flange 19.

It is may be placed to pry are utilized asengagement 5 portions for lifting the plug from position, while the plug can be utilized for lifting the spout from position. Furthermore, the spout can be seated securely in position by pressing downward upon the closure plug and the closure plug may be seated by pressing downwardly upon the spout.

In the modified form shown in Figures 4 and 5, the shape of the pouring spout member and the plug reclosure member is essentially the same as before, and the parts are combined into a unitary structure having mutual supporting and cooperating partsr In'the form of Figure 5, a modified form of initial seal is provided. Inthis case the wall I 0 about the discharge opening has an inwardly extending ledge terminating in a cylindrical flange II. A seal comprises a cylindrical wall 32 with a flange 33 which is seated upon the ledge Ill, and a bottom portion Ila located within the scoring Ha. In this case the walls 3| and 32 are fitted tightly together so that this member cannot bewithdrawn after it has once been inserted. Such a type of initial tamper-proof closure is advantageous as it is possible to fill the container through the opening in the wall ii and then insert the plug in position. This plug canfrom the exterior thereafter without damage to other parts of the structure providing the opening.

It is obvious that the invention is not limited to the particular forms shown, but that it may be employed in many the appended claims. Having thus described the invention, what I claim as new and desire to secure by Letters Pateat is: V

1; The combination with a containerhaving a closure wall with means for providing a discharge opening, and a friction seat around said opening, and a device including a pouring spout member and a reclosure member connected flx edly together, each member having a portion cooperative with the friction seat and each operative as a grip for removing the other member from its cooperation with the friction seat, and a swinging bail pivotally mounted on the container and pivotally engaged with said device for guiding either of said member portions to said friction seat.

2. The combination with a container having a closure wall with means for providing a discharge opening, and a friction seat around said opening, and a device including a pouring spout member and a friction reclosure member connected fixedly together, each member having a portion frictionally cooperative with the friction seat and each operative as a thrust member for'forcing the other member into frictional engagement with said friction seat.

3. The combination with a container having a closure wall with means for providing a discharge opening, and a friction seat around said opening, and a device including a pouring spout member and a reclosure member connected fixedly together, each member having a portion cooperative with the friction seat and each operative as a grip for removing the other member from its cooperation with the friction seat, and a swinging bail pivotally mounted on the container and pivotally engaged with said device for guiding either of said member portions to said friction seat, said portions being spaced like distances from the pivot connection between the device and hail so that each is presented to the friction seat and so that the closure cap does not obstruct the spout.

4. The combination with a container having a closure wall with means for providing a discharge opening, and a opening, and a device including a pouring spout member and a reclosure member connected flxedly together and each having a substantially cylindrical portion cooperative with the friction seat, the spout member having a pouring lip leading from the cylindrical portion and a rear portion opposite the pouring lip, the reclosure member being located adjacent and secured to said rear portion.

5. The combination with a container having aclosure wall with means for providing a discharge opening, and a friction seat around said opening, and a device including a pouring spout member and a reclosure member connected fixedly together and each having a substantially cylindrical portion cooperative with the friction seat, the spout member having a pouring lip leading from the cylindrical portion and a rear portion opposite the pouring lip, the reclosure member having a peripheral flange, and said rear portion being curled about said flange.

6. The combination with a container having a closure wall provided with a depressed portion forming a friction seat, the bottom of said depressed portion being scored so that the metal may be ruptured and a pouring opening formed, a device including a pouring spout member and a reclosure member, each having a substantially cylindrical portion adapted to engage the friction seat, the pouring spout member having a pouring lip, said reclosure member being connected to said pouring spout member at a point peripherally spaced from said pouring li wmmnrum.
